AEG AXP26U339CW review
AEG Comfort 6000 AXP26U339CW 9000 BTU Portable Air Conditioner
By Tom Calder
AEG's replacement for the ChillFlex Pro AXP26U338CW: the same 2.6kW class, now with app control, and an honest 64dB(A) on its label. The catch is supply. AEG has dropped portable air conditioners from its UK site, AO was the only UK seller listing it, and it was out of stock on Amazon in October 2026. AEG's room-size claim of 31–35m² is too generous for 2.6kW, so size it as a bedroom unit.

Our review
A cooling-only 9,000 BTU portable from AEG, placed on the EU market in January 2023 as the Comfort 6000, with Wi-Fi app control added over the ChillFlex Pro it replaced. Its label is clear: 2.6kW, class A, 64dB(A). Buying one is the hard part, because AEG has stepped back from portable air conditioning in the UK. It suits someone who finds one discounted for a bedroom and is content to rely on the retailer for support.
What the numbers mean
The EU label fiche for model AXP26U339CW, product number 950011610, gives 2.6kW of cooling, about 8,900 BTU, so the 9,000 BTU on the box is honest. The EER is 2.6, class A, with 1.0kWh an hour in cooling under standard test conditions: about 26p an hour at the Ofgem price cap unit rate of 26.32p per kWh for October to December 2026, less once the compressor cycles. Sound power is 64dB(A) indoors, mid-table for a single-hose unit. The refrigerant is R290.
In a British home
At 2.6kW this is a bedroom or small living-room machine. AEG's own room-size claim runs into the low thirties of square metres; Pro Breeze rates its own 2.6kW unit for up to 22m², a more realistic guide. AEG's manual is candid that pushing air out through the hose draws warm air in from neighbouring rooms, so the room may never quite reach the set temperature. The manual lists the box contents as an exhaust hose that stretches from 38cm to 150cm, a flat window adaptor and a drain hose, with the sealed window kit (AWKIT5) as an optional extra; AEG's Danish page says a kit is included, so check what your listing supplies. There is no heating mode.
The supply problem
This decides whether to buy. AEG's UK site no longer lists portable air conditioners, and in October 2026 the only UK retailer we found carrying this model was AO, with the Amazon listing out of stock. With the brand out of the category here, expect returns to run through the retailer and repairs through AEG's general service line. If you buy, keep the receipt, note the model and PNC (950011610) from the rating plate, which the manual says a service centre will ask for, and register it with AEG so the warranty is on record.
How it compares
The AEG ChillFlex Pro AXP26U338CW it replaced has the same 2.6kW, 1.0kWh an hour and 64dB(A), a better EER of 3.0 and no app; it too has been withdrawn, so neither AEG is a safe long-term buy. The Pro Breeze 9000 BTU Smart matches the AEG's label almost exactly (2.6kW, EER 2.6, 1.0kWh an hour, 65dB(A)), comes with two window kits, weighs 26.5kg, and was taking pre-orders for February 2027 from a company still in the market. For winter use too, the MeacoCool Pro 9000 CH adds a heat pump and UK-based support. More options are on the comparison page.
Living with it
The Amazon UK listing gives 31.5kg, heavy for a 9,000 BTU unit, so it stays on one floor. Control is from the panel, a remote and an app; the manual points to Electrolux's app for set-up and says the Wi-Fi module works only on 2.4GHz. Vacuum the two air filters every two weeks of use, the manual says, or wash them below 40°C if very dirty; a filter light comes on after 250 hours. Dry mode drains through its own outlet and the supplied hose, and a P1 code means the tank needs emptying. Plug it straight into a wall socket: the manual rules out extension leads. Returns run on the retailer's terms, since AEG does not sell it direct in the UK.
Our verdict
Worth buying only if a UK retailer offers it at a clear discount for a bedroom or small living room and you accept that support will come from the shop rather than the brand. At list price the Pro Breeze does the same job with a company behind it, and the Meaco adds heating. Before any of them, read whether a portable air conditioner is worth it: for many bedrooms a fan and daytime shading are enough.

Who shouldn't buy this
Don't buy it if you want a model with dependable UK stock and support: Meaco and De'Longhi sell and service theirs directly.

Questions
Is the AEG AXP26U339CW still available in the UK?
Barely. AEG's UK site no longer lists portable air conditioners, and in October 2026 AO was the only UK retailer we found listing this model, with the Amazon listing out of stock. Treat any stock you find as end-of-line.
How loud is the AEG Comfort 6000 AXP26U339CW?
Its energy label gives 64dB(A) sound power indoors in cooling mode, the same as the ChillFlex Pro before it and typical for a single-hose portable. Lower figures in listings are sound pressure measured at a distance and are not comparable.
What size room will the AEG AXP26U339CW cool?
Its label rates it at 2.6kW, about 8,900 BTU, a bedroom or small living-room unit. AEG's own figure in the low thirties of square metres is optimistic; Pro Breeze rates its own 2.6kW unit for up to 22m², a more realistic guide.
What is the difference between the AXP26U339CW and the AXP26U338CW?
The 339 is the newer Comfort 6000 with Wi-Fi app control; the 338 is the ChillFlex Pro without it. Both are 2.6kW, 1.0kWh an hour and 64dB(A) on their labels; the older 338 has the better EER, 3.0 against 2.6. AEG UK has withdrawn both.
How much does the AEG AXP26U339CW cost to run?
About 26p an hour at full output, from the label's 1.0kWh an hour at the Ofgem price cap rate of 26.32p per kWh for October to December 2026, and less once the thermostat is cycling the compressor.
